Make a body to jump?

Postby sickman » Thu Oct 09, 2008 9:12 am

I want to make a body to jump, but apply_force makes it act weird (it never slows down).

Is there a "proper way" to make the body jump? Or did I do the force applying wrong?

Try applying an impulse instead.

Forces act continuously until you reset them. Impulses modify the object's velocity immediately. Impulses are a much better way to implement things like jumping or guns firing.

Yeah, it's the shorthand used in all the physics equations. Someday I'll refactor all the naming to make it more clear. I swear :(

j is the impulse expressed as a vector in absolute coordinates. r is the offset from the center of gravity of the body, also expressed in absolute coordinates.
